CR-VANET (Cognitive radio-vehicular Ad-Hoc Network) can mitigate channel resource shortage and congestion in VANET. For CR-VANET, with the consideration of fast topology changes and Pus'activities, the existing routing protocols or schemes in VANET or cognitive radio networks (CRAHNs) can not be directly applied into CR-VANET. Therefore, we propose a jointly routing algorithm of CRVANET in urban single-lane expressway for minimizing end-to-end delay (MDCR-VANET). With the consideration of characters of single-lane urban expressway and delay in CRAHNs and VANET, we formulate the objective function as non-linear integer programming, which is NP-hard. Our algorithm uses the geography based greedy forwarding method to ensure the minimum transmission delay and store-forward delay. For the channle selection, we propose a heuristic method to select appropriate channel. Through extensive simulations and comparisons of stateof-the-art protocols, we prove that our algorithm can achieve less end-to-end delay.
认知无线车载自组织网络(Cognitive radio-vehicular Ad-Hoc Network, CR-VANET)可以缓解VANET中的信道资源短缺和拥塞问题。对于CR-VANET,考虑到拓扑结构的快速变化和Pus的活动,现有的路由协议或方案在VANET或认知无线网络(CRAHNs)中不能直接应用于CR-VANET。为此,我们提出了一种城市单车道高速公路上最小化端到端延迟的联合路由算法(MDCR-VANET)。考虑到单车道城市快速路的特点以及高速公路和高速公路的延迟,将目标函数化为非线性整数规划,具有np困难。该算法采用基于地理的贪婪转发方法,以保证最小的传输延迟和存储转发延迟。对于信道选择,我们提出了一种启发式方法来选择合适的信道。通过大量的模拟和比较最先进的协议,我们证明了我们的算法可以实现更少的端到端延迟。

In this paper, we analyze the susceptibility of the Band-to-Band tunneling (BTBT) current subjected to the interface traps in silicon tunnel field effect transistors (TFET). The study quantifies the BTBT current against the types of interface traps (donor or acceptor), its density (NtD or NtA), and the corresponding trap energy level (Etrap) within the forbidden gap. It is observed that the acceptor-type traps deteriorate the BTBT mechanism in an n-TFET while it improves the same in a p-TFET. A similar, however, opposite observation is obtained for the donor-type traps. Further, it is observed that a small trap density (1×1011 cm−3) has little impact on the BTBT (due to large band-gap in silicon) while a larger value (5×1012 cm−3) changes the BTBT substantially. Moreover, it is shown that the trap energy location (Etrap =3D 1.0 eV) increases BTBT when closer to the conduction band for n-TFET while for p- TFET, a similar observation is made when Etrap is located closer to the valence band.
本文分析了硅隧道场效应晶体管(ttfet)中受界面陷阱影响的带对带隧道电流的敏感性。该研究根据界面陷阱的类型(施主或受主)、其密度(NtD或NtA)以及禁隙内相应的陷阱能级(Etrap)来量化BTBT电流。观察到,受体型陷阱在n-TFET中恶化了BTBT机制,而在p-TFET中则改善了BTBT机制。然而,在供体型陷阱中得到了类似的相反的观察结果。此外,观察到小的陷阱密度(1×1011 cm−3)对BTBT的影响很小(由于硅中的带隙很大),而较大的陷阱密度(5×1012 cm−3)则会显著改变BTBT。此外,n-TFET的陷阱能量位置(Etrap =3D 1.0 eV)越靠近导带,BTBT就越高,而p- TFET的陷阱能量位置越靠近价带,BTBT也会增加。

An automated plant identification is necessary to identify plants, especially rarely seen ones. In this paper a framework to identify plant species based on leaf's characteristics is introduced. First, 31 features of leaves from 13 species are extracted that represents color, shape and texture of the leaves. Then, the features are selected according to their correlation to the class label. The data with 25.8% pruned features are then used to train a feedforward neural network. The network is trained and tested using 975 images by implementing 10-fold mechanism yields 95.54% accuracy.

With the growing demand for more efficient power converters with higher power densities, usage of new materials like Silicon Carbide (SiC) are getting increasingly popular. The availability of SiC devices has led to more efficient converters owing to beneficial features such as having lower internal resistance and faster switching times compared to Si based devices. SiC cascode and SiC MOSFET are among the most promising candidates. The SiC cascode consists of a JFET (normally ON) in series with a MOSFET. In this study, operation modes for Zero Voltage Switching (ZVS) in half bridge topology have been analyzed. SiC cascode, SiC MOSFET and Si IGBT device with very similar voltage and current ratings are chosen and simulated using Pspice. The results are compared with regard to efficiency, switching performance and conduction losses in half bridge topology at different frequencies from 38.41 kHz to 50 kHz. The turn on and turn off characteristics obtained from simulation are provided and compared to each other. All power devices are assumed to be at ZVS condition. SiC cascode turned out to be the most efficient among all, and SiC MOSFET was better than Si IGBT in terms of switching performance. In the light of these findings, it is logical to assume that in the future we might see more SiC devices used in induction cookers.

This paper presents an investigation of numerical modeling of SiGe HBT (Silicon-Germanium heterojunction Bipolar Transistor). For this, we consider three models: the so called Drift Diffusion Model (DDM), the Isothermal Energy Balance model (EB) and the Non-Isothermal Energy Balance model (NEB). The considered devices correspond to the BiCMOS6G 0.35pm industrial processes and are dedicated to radiofrequency applications. The numerical device modeling considers Technology CAD (TCAD) simulation. The DDM model describes the classical transport in semiconductor devices. The energy balance model describes the energy transport. This model is coupled with thermionic emission transport. The NEB model permits to take into account the non-uniform distribution of the carrier's temperature. Some typical numerical results are presented such as the current-tension curve, Gummel curves and cutoff frequency for the three models. For submicron devices, it is clear that it is necessary to take into account the phenomena such as thermionic emission and the non-uniform distribution of the carriers.

Helicopters utilization is not limited to military and surveillance applications but they are also used for transporting heavy loads from one place to another because of their vertical takeoff and landing (VTOL) capabilities. However slung load is drastically affected by disturbances around the system making difficult for helicopter to regain control. Tip vortices at the blades induce velocity which not only effect blades but also degrade performance of the whole system by creating vibrations. This paper proposes control technique based on sliding mode control utilizing linear matrix inequality to keep payload unaffected in the presence of rotor downwash and time varying air disturbances during hovering. With the help of proposed controller desired trajectory is achieved due to its robustness and variable control structure.
直升机的使用不仅限于军事和监视应用,而且由于其垂直起降(VTOL)能力,它们还用于将重物从一个地方运送到另一个地方。然而,悬挂载荷受到系统周围干扰的极大影响,使直升机难以重新获得控制。叶尖涡在叶片上产生速度,不仅影响叶片,而且通过产生振动降低整个系统的性能。本文提出了一种基于线性矩阵不等式的滑模控制技术,在旋翼下洗和时变空气扰动存在的情况下保持有效载荷不受影响。利用该控制器的鲁棒性和可变控制结构,实现了理想的运动轨迹。

Evaluation performance of multicarrier system using hybrid schemes to support 5G technology 采用混合方案支持5G技术的多载波系统性能评估

The major limitation of the multicarrier system in 5G is the peak-to-average power ratio (PAPR). PAPR is a crucial parameter for representing 5G waveform candidates, such as UFMC, FBMC, and GFDM. The higher PAPR induces the signal to be in the saturation region of high power amplifier (HPA). Hybrid PAPR diminishment technique is discussed in this paper. To attack PAPR problem, in this paper, a new adaptive level algorithm with a hybrid PAPR reduction scheme is proposed. A hybrid optimized repeated clipping and filtering combined with a companding scheme (Hybrid-ORCC) is presented. The main objective of this system is to reduce PAPR of OFDM with a minor degradation in the Bit Error Rate (BER) performance. The ORPC PAPR value has been reduced by 7.5 dB and then the Hybrid-ORCC reduce the final PAPR by 2 dB. PAPR reduction plays an important role in diminishing the system power consumption. Extensive MATLAB simulations show that the hybrid technique outperforms the conventional clipping techniques by reducing the PAPR to its optimal value.
5G多载波系统的主要限制是峰值平均功率比(PAPR)。PAPR是表示5G候选波形(如UFMC、FBMC和GFDM)的关键参数。较高的PAPR使信号处于高功率放大器的饱和区。本文讨论了混合PAPR消减技术。为了解决PAPR问题,本文提出了一种混合PAPR约简方案的自适应水平算法。提出了一种混合优化的重复滤波和压缩方案(hybrid - orcc)。该系统的主要目标是在降低误码率(BER)性能的同时降低OFDM的PAPR。ORPC的PAPR值降低了7.5 dB,然后Hybrid-ORCC将最终的PAPR降低了2 dB。降低PAPR对降低系统功耗起着重要的作用。大量的MATLAB仿真表明,混合技术通过将PAPR降低到最优值而优于传统的裁剪技术。

Static test is an important test to perform during a rocket operation testing. As the name indicates, it is performed under a static condition. The main information to obtain from this type of test is the rocket thrust force. This paper describes a method to measure the thrust force based on the utilization of a load cell sensor. Unlike the previous analog measurement methods, this paper proposes the use of digital measurement method. The measurement results are to be displayed in a form of graphics and tables in a real-time way, so that the distance traveled by rocket as well as its speed can be estimated. An estimation method based on the optimum thrust force approach has been explored. The measurement data can either be stored in a database system using Microsoft Access or in a microSD card to facilitate the flexibility in transferring data to other equipments.
静态试验是火箭运行试验中的一项重要试验。顾名思义,它是在静态条件下执行的。从这种类型的试验中获得的主要信息是火箭推力。本文介绍了一种利用称重传感器测量推力的方法。与以往的模拟测量方法不同,本文提出采用数字测量方法。测量结果将以图形和表格的形式实时显示,以便估计火箭行进的距离和速度。探索了一种基于最优推力法的估算方法。测量数据既可以存储在使用Microsoft Access的数据库系统中,也可以存储在microSD卡中,以便灵活地将数据传输到其他设备。
